Outdated Product
Double-circuit gas boiler of low power with a closed type combustion chamber and a microprocessor control system. It is the youngest model from the 2015 Logamax U072 line. It is distinguished by affordable cost, moderate overall dimensions of the case, a convenient control system with a clear LCD screen and decent efficiency. It is positioned as an affordable product of the middle price category, designed for organizing heating and hot water supply systems in private houses / cottages, city apartments, office and utility rooms with a total area of up to 96 m2. Due to the use of a closed combustion chamber and a system of forced flue gas removal by a fan, the Buderus Logamax U072-12K boiler does not require the use of a high chimney system and can be installed directly in residential areas....It is a highly integrated solution that includes an 8 liter expansion tank, an automatic three-stage circulation pump, a reliable safety valve, a flow sensor, as well as a complete set of control and safety devices. The heating circuit heat exchanger is made of copper, hot water is heated in a high-quality stainless steel plate apparatus.

A good boiler, the quality of the plastic could be improved and the instructions added.
22 October 2017 
Good model. The manufacturer forgot to mention that it can only be connected to UPSs with a solid neutral, otherwise the control board burns out. All boiler malfunctions are due to violations of operating conditions.
Clear, simple menu, economical.
1. The user manual forgot to mention that the boiler operates with a hard neutral.
2. The user manual provides few explanations regarding possible malfunctions that are not indicated by an error code.
3. The plastic latches break quickly, indicating poor quality plastic or a design flaw.
